SPECIFICATION forming part of Letters Patent No. 791,630, dated June 6, 1905.

' Application filed Jul-y 30, 1904:. Serial No. 218,892.

To all whom it may concern.-

Be it known that I, MORGAN M.'LEWIS, a

citizen of the United States, residing at the city of Battlecreek, county of Calhoun, State of Michigan, have invented certain new and useful Improvements in Boats, of which the following is a specification.

This invention relates to improvements in boats.

It relates particularly to improvements in 7 the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed outin the'claims. Y

A structure embodying the features of my invention is clearly illustrated in the accompanying' drawings, forming a specification, in which Figure 1 is a detail "longitudinal sectional view of my improved boat, taken on a line corresponding to line 1 1 of Figs. Qand 3. Fig. 2 is an enlarged detail sectional view taken on a line corresponding to line2 2 of Fig. 1. Fig. 3 is an-enlarged detail sectional view taken on a line corresponding to line 3 3 of Fig. 1. Fig. 4is an enlarged perspective view of one of the fasteners D. n

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, A is the keel of a boat. B the shell or skin and (l the ribs. The skin B is made of strips of sheet metal, which are preferably joined together by cloupart of this bl'e seamsB. The keel is secured to the skin by fasteners D, which are inserted through slot-like holes in the skin and keel. teners D are made up ofstrips of sheet metal, which are folded inwardly to form a head 11,

and-the ends 0K are broughttogether to form the The fasshaftof the fastener. (See Fig. 4.) After inserting through the skin and keel from the in side the ends of the shank are spread laterally are lapped upon the forward edge of the inner bow-piece A and secured thereto by brads or nails. (See Fig. 2.) These-overlapping joints are then preferably given a Wash of solder to make the same perfectly water-tight. V

Theouter bow-piece or keel extension A, which corresponds in shape with the inner bow-piece A, is provided with a trough 0;, of sheet metal, on its inner edge, adapted to fit over the inner bow-piece, with the shell or skin strip secured thereto, asdescribed. The

outer-bow-piece or keel extension A is secured in position by nails or brads, which are driven through the sides of the trough a into the inner bow-piece A, and also by the fasteners D, which are arranged therethrough and through the inner bow-piece, as clearly appears in Figs. 1 and 2. The union of the sides of the trough to the skin may be made" water-tight by soldering. which is common to the keel and its bow and stern extensions, is then secured in place by suitable screws. This shoe covers the ends d" of the fasteners and prevents the loosening of the retaining-nails. It would also hold A metal shoe (0.

: thefasteners quite securely if the nails were is secured to the skin of the boat in a very strong and rigid manner and the fastenings are so arranged that they are not liable to corrode and form leaks. This is also true of the bow-pieces. When the parts are secured as I have described, they are not likely to become loosened by shrinking and swelling of the wood parts. The wood parts are not weakened,as would occur if holes were bored through the same to receive bolts of suflicient size to meet the required strain, and the necessity for any rubber or other gaskets or packings is entirely overcome.

The fastenings D maybe made up of pieces of waste material, which is a considerable item in the reduction of the expense of manufacture. The fasteners have large flat heads, so tgat they are not liableto pull through the s in.

I have illustrated my improved boat in detail in the form preferred by me on account of its structural simplicity and economy. I am aware, however, that it is capableof considerable variation in structural details without departing from my invention.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. Inaboat, the combination of a skinmade of longitudinal strips of sheet metal, suitably seamed together; a keel arranged on the outside of said skin; an inner end piece to which the ends of said longitudinal strips are secured by overlapping thereon, and nailing; an outer end piece having a sheet-metal trough .on its rear edge, fitted over said inner end piece and secured thereto by nailing through the sides of said trough; fasteners consisting of pieces of sheet metal folded to form heads,

and the ends brought together to form shafts, which shafts are arranged through suitable slits and spread laterally and secured by nailing therethrough; and a metal shoecommon to said keel and end pieces, secured thereto, for the purpose specified.

2. In a boat, the combination of a skin made of longitudinal strips of sheet metal, suitably seamed together; a keel arranged on the outside of said skin; an inner endpiece' to which the ends of said longitudinal strips are secured by overlapping thereon, and nailing; an outer end piece having a sheet-metal trough .on its rear edge, fitted over. said innerv end piece and secured thereto by nailing through the sides of said trough; and fasteners consisting of pieces of sheet metal folded to form heads, and the ends brought together to form shafts, which shafts are arranged .through suitable slits and spread laterally and secured by nailing therethrough, for the purpose specified.

3. In a boat, the combination of a skin made of longitudinal strips of sheet metal, suitably seamed together; an inner end piece to which the ends of said longitudinal strips are secured by overlapping thereon, and nailing; an outer end piece having a sheet-metal trough on its rear edge, fitted over said inner end piece and secured thereto by nailing through the sides of said trough; fasteners consisting of pieces of sheet metal folded to form heads, and the ends brought together to form shafts, which shafts are arranged through suitable slits and spread laterally and secured by nailing therethrough, for the purpose specified.

4. Inaboat, the combination of a skin made of longitudinal strips of sheet metal, suitably seamed together; aninner end piece to which the ends of said longitudinal strips are secured by overlapping, thereon, and nailing; and an outer end piece having a sheet-metal trough on its rear edge, fitted over said inner end piece and secured thereto by nailing through the sides of said trough, for the purpose specified.

5. In a boat, the combination of a skin of sheet metal; a keel or the like arranged on the outside of said skin; fasteners consisting of pieces of sheet metal folded to form heads, and the ends brought together to form shafts, which shafts are arranged through suitable slits in said skin and keel from the inside, and their ends spread laterally upon said keel and secured thereto by nailing therethrough; and a metal shoe secured over the ends of said fasteners, for the purpose specified.

6. In a boat, the combination of a skin of sheet metal; a keel or thelike arranged on the outside of said skin; fasteners consisting of pieces of sheet metal folded toforln heads, and the ends brought together to form shafts, which shafts are arranged through suitable slits in said skin and keel from the inside and their ends spread laterally upon said keel; and a metal shoe secured over the ends of said fasteners, for the purpose specified.

-7. .In a boat, the combination of a skin of sheet metal; a keel or the like arranged on the outside of said skin; and fasteners consisting of pieces of sheet metal folded to form heads, and the ends brought together to form shafts, which shafts are arranged through suitable slits in said skin and keelfrom the inside, and their ends spread laterally upon said keel and secured thereto by nailing therethrough, for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
